Constructor Detail

GeometricBrownianMotionOracle

public GeometricBrownianMotionOracle()

A dummy oracle which generates values using a geometric Brownian motion. Using default parameters. Caution: The object is initialized with LocalDateTime.now(). This will result in different Oracles each time the object is instantiated.

GeometricBrownianMotionOracle

public GeometricBrownianMotionOracle(LocalDateTime initialTime)

A dummy oracle which generates values using a geometric Brownian motion. Using a given initial time and default parameters.

Parameters:

initialTime - The date corresponding to the initial time of the oracle. Valuation prior this time is not provided.

GeometricBrownianMotionOracle

public GeometricBrownianMotionOracle(LocalDateTime initialTime,
                                     double initialValue,
                                     double timeHorizon,
                                     double riskFreeRate,
                                     double volatility,
                                     int numberOfPaths)

A dummy oracle which generates values using a geometric Brownian motion. Using a given initial time and default parameters.

Parameters:

initialTime - The date corresponding to the initial time of the oracle. Valuation prior this time is not provided.

initialValue - The initial value.

timeHorizon - The time horizon in ACT/365 from initialTime.

riskFreeRate - The drift.

volatility - The volatility.

numberOfPaths - The number of simulation path to generate.
